Is it free? They don't mention home energy storage as a potential application. I would have no trouble believing that the extra electrical work and additions to the foundation beyond what's involved in a traditional cement foundation cost a whole lot less than a lithium battery.
I'd also be concerned about problems with the foundation. Foundations crack and suffer water damage. My mom just had her foundation repaired. What risk is there that the electricity can discharge?
Like if it's as simple as running some inexpensive cables through the cement mix and plugging in a little box, awesome. But I suspect this is hardly the case, and I suspect the sheer volume of cement needed to be practical/useful is quite high for residential use.
